Characterization of the Cis and Trans Acting Factors that Influence p53 IRES Function
(2018-03-07)p53 is a nodal tumor suppressor protein that acts as a major defense against cancers. Approximately 50% of human tumours have mutations in p53 gene. Among its myriad features, the most distinctive is the ability to elicit ... -
Characterization of the transsulfuration enzyme Cystathionine beta-synthase as a novel regulatory node in the sulfur metabolism of Mycobacterium tuberculosis
Methionine and cysteine metabolisms are important for the survival and pathogenesis of Mycobacterium tuberculosis (Mtb). The transsulfuration pathway converts methionine to cysteine and represents an important link between ... -
Characterization of Thymocyte Subpopulations and Mechanistic Insights during Various Modes of Thymic Atrophy
T lymphocytes along with B lymphocytes constitute the adaptive immune system, which is critical for host defence. The progenitors of T cells arise in the bone marrow and the sequential development of T cells occurs in the ... -
Characterization of Visual Stimulus-Induced Gamma Oscillations as Signatures of Mechanisms Underlying Healthy Aging and Disease
Neural oscillations are rhythmic fluctuations in the electrical activity recorded from the brain that convey important information about brain function. Gamma oscillations, which refer to the 30–80 Hz frequency range, are ... -
Characterization of XRN2-mediated microRNA turnover mechanism and its pathophysiological significance in eukaryotes
MicroRNAs (miRNAs) are endogenous, small non-coding RNAs that are extensively involved in the posttranscriptional regulation of gene expression in eukaryotes. Comprehensive studies on miRNA expression and function have ... -
Characterizing the link between dynamics and function in proteins that violate the structure-function paradigm
The structure-function paradigm states that the three-dimensional structure of a protein is dictated by its amino acid sequence, which influences its function. However, this paradigm fails to explain the behaviour of ... -
Characterizing the role of claudins in C. elegans neurons
Cell adhesion molecules (CAMs) play important roles in neurons, contributing to nervous system development, synapse formation and plasticity. A subset of CAMs, Claudins, known for their roles at tight junctions, remain ... -
Characterizing the viral factors and host determinants that control Dengue virus infection and pathogenesis
Background – Dengue virus is a mosquito-borne flavivirus that is the causative agent for dengue fever, which progresses to dengue shock syndrome in many patients. It is estimated that around 390 million dengue infections ... -
Chimeric Virus Like Particles as Nanocarriers for Antibody Delivery in Mammalian Cells & Role of Groundnut Bud Necrosis Virus NSs in Viral Life Cycle
(2018-08-02)Knowledge of the dissociation constants of the ionizable protons of weak acids in aqueous media is of fundamental importance in many areas of chemistry and biochemistry. The pKa value, or equilibrium dissociation constant, ... -
Cholinergic-receptor-independent modulation of intrinsic properties of subicular neurons through inhibition of hyperpolarization-activated cyclic nucleotide-gated channels
Acetylcholine release is vital in tuning the hippocampal theta oscillations. Subiculum, the output region of the hippocampus endowed with different neuronal subtypes, also generates theta oscillations during arousal and ... -
Circuit mechanisms of itch modulation: from physiology to pathology
Itch is a distinct somatosensation, evoked by chemical and mechanical pruritogens or psychosomatic factors. It detects harmful sensory stimuli and triggers scratching to remove irritants from the skin. However, chronic ... -
Climate Change Mitigation And Adaptation In Indian Forests
(2014-10-10)Research leading to this thesis aims to assess the policy relevant mitigation potential of Indian forests as well as aims to assess the impact of climate change on carbon stocks, vegetation boundary shifts, Net Primary ... -
Climate-Growth Relationships of West Himalayan Fir (Abies pindrow) along an Altitudinal Gradient in Northwestern Himalaya
Climate change which includes an increase in temperature, changes in precipitation, retreating of glaciers, has a significant impact on ecosystem dynamics and the social communities. High mountains around the globe are ... -
Cloning and Expression of a Diagnostic Antigen for Invasive Amoebiasis
(Indian Institute of Science, 2005-04-29)A crude extract of axenically grown amoebae was used as antigen in order to develop an AB microELISA for the detection and quantitation of E. histolytica-specific IgG antibodies. This ELISA was used to screen individual ... -
Collective escape dynamics of fission-fusion groups in the wild
Collective movement is a fundamental process affecting the survival and reproductive success of group-living animals. Many of the hypothesized benefits of grouping such as predation evasion and foraging efficiency may ... -
Colony Founding And The Evolution Of Eusociality In Primitively Eusocial Wasp, Ropalidia Marginata
(Indian Institute of Science, 2005-08-08)Many animals live in societies of varying degrees of organization. Some individuals in these societies seem to sacrifice their own fitness to increase the fitness of some others. Understanding the forces that mould the ... -

Comparative evaluation of retrograde regulatory proteins (Rtg1p, Rtg2p, and Rtg3p) of Saccharomyces cerevisiae and Pichia pastoris and identification of P. pastoris RtgXp as a novel regulator of multiple metabolic pathways
Our work demonstrates for the first time that PpRtgXp, a basic, helix-loop-helix (bHLH) protein, is a global regulator of carbon metabolism. PpRtgXp constitutively localizes inside the nucleus. Despite lacking the C-terminal ... -
A Comparative Study On The Sensitivity Of Cells Of Different Lineages To Plant Ribosome Inactivating Protein - Abrin
(2010-12-08)Proteins with selective toxicity have been investigated for use in many ways. One class of proteins, ribosome-inactivating proteins (RIPs), is found throughout the plant kingdom as well as in lower organisms like certain ...
